Hello, We are attempting to use this module. On the checkout_payment.php page, we end up with https://i.gyazo.com/de89d794624ee52ecd6baa5e7dc4e529.png We cannot enter any CC details, nor select a credit card type. Upon hitting continue we will get "error_message=Please+select+a+payment+method+for+your+order." We followed the original installation, then also tried j0ec00l2k's suggestions for making it compatible. Using PHP 5.6. Any help would be appreciated greatly.
